* Heal peer-ID rotation: rebind link on verified announce, retire ghost When a peer relaunches it rotates its ephemeral peer ID, but a still-open BLE connection kept its stale peripheral/central→peerID binding for the reachability retention window (~45-60s). Until it aged out, the other side showed a duplicate ghost peer and dropped the rotated peer's direct announces as spoofing attempts. Root cause: the ingress guard rejected a direct announce whose claimed sender differed from the link binding before signature verification could ever see it, so the binding could never heal. - Ingress guard: let a mismatched direct announce through, attributed to the claimed sender; REQUEST_SYNC keeps the strict binding check. - Bind sites: raw (pre-verification) announces may only bind unbound links, never rebind bound ones — rebinding now requires the announce handler's signature verification to pass. - On a verified direct announce whose ingress link is bound to a different peer, rebind the link to the announced ID and retire the rotated-away ID immediately (registry + gossip + UI), mirroring handleLeave. - BLELinkStateStore.bindPeripheral: drop the previous peer's reverse mapping on rebind so the retired ID no longer claims the link. Fixes #1387 Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Contain forged-directness rebinds: no identity steal, per-link cooldown The announce signature does not authenticate directness (TTL is excluded from signing because relays mutate it), so a bound peer could replay another peer's fresh signed announce with its TTL restored and reach the rotation rebind path. Contain what such a replay can do: - Refuse a rebind when the claimed identity already owns another live link — a replayed announce can no longer steal a connected peer's binding or route its directed traffic to the replaying link. - Allow at most one rebind per link per cooldown window (60s) so two identities cannot fight over a link in a replay flip-flop, with each flip retiring the other peer. A replay against an identity with no live link remains possible, but that capability already exists today on unbound links, where any raw direct announce binds pre-verification.
